Advice please: Te Jutsu, Ken Jutsu, Kobudo, etc - etc

Hi all,

I know sweet FA about Japanese martial arts and after some searching here at Bullshido and Google Fu, I don't seem to have much to go on when assessing the following NZ school/Teacher.

Theres a link below that rings a few alarm bells, and I have a mate who is all about waving sharp things around and going to weekend camps. Before he hands over his cash - and stops getting my ear about this...

First , has anyone trained with this mob - feedback?
Second, does anyone know of Ray Potrer and if he's legit. There seems to be a lot "Dans" getting thrown around.

None of this says anything good. Play to play organizations and no real art names. The art names don't meaning anything -- they're just generic. "Karate" could mean anything. And the few pictures I see don't look good at all.

Be nice if there was a kobudo organization like there that's like the Dog Brothers.

I'd love to learn me some full contact sparring with the tonfa.

I made a video of this match from last weekend:

In the early days of the Dog Brothers, there were Kobudo folks with tonfas and nunchaku and whatnot. They didn't do so well. Aside from the training (usually kata only), the footwork doesn't seem well suited for weapon fighting.

I'm wondering if these guys warrant a bit of a prod - MABS investigation - ask some questions? Kiwis are usually a fairly pragmatic and down to earth bunch, this just seems offensive. I'll have a go and cut my teeth on this if others more experienced BS persons think its worthwile. I've found some other dubious operators with links to him - weird associations of other try-hards that seem to gravitate to one another.
